'EU might be only answer' against US surveillance concerns

David Davis has been a candidate for the leadership of the British Conservative party, has called for complete withdrawal from the European Union and has also made a name for himself as a civil liberties campaigner.

But during a HARDtalk interview he told Gavin Esler, the European Union "might be the only answer" against invasion of privacy from the US.

He also said the UK should not withdraw from the European Convention of Human Rights, despite concerns raised by the Home Secretary Theresa May.
